Does one exist? It'd be handy. An error dump/game message dump too. I put a fedora on a Krong altar and it said he cursed it, but the fedora was unchanged stat-wise - only the name and description changed. I can't see exactly what Krong DID, if anything. This is where a detailed log/debug mode would be handy, I think.
Start the game with -debug-flag as an append. Like from steam launch options, or from a shortcut. It adds some commands like level up, go up/down stairs, fill inventory, show map
